Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Such as Fig. 2～shown in Figure 6, a preferred embodiment that provides for the utility model.
Present embodiment provides a kind of clip 100, be used for fixed mask cover 200, comprise a support chip 1 and extend left intermediate plate 2 and the right clamping piece 3 that bending forms by described support chip 1 both sides, form crack 4 between described left intermediate plate 2 and the described right clamping piece 3, the described crack 4 described radome 200 that can be fixedly clamped.So, clip 100 volumes are little, and it is little to take circuit board 500 spaces, according to the shape of the chip that shields, cooperate arrangement by a plurality of clips 100, described radome 200 can be fixed in the described crack 4, cover on the chip that needs shielding highly versatile, good reliability.Even if when maintenance, also described radome 200 directly can be taken off from clip 100, simple and convenient, be easy to safeguard.
Further, be fixedly clamped more reliably in the crack 4 of described clip 100 in order to make described radome 200, the ratio of the sidewall thickness D1 of the width D 2 of crack 4 and described radome 200 is arranged between 0.8 ~ 0.9.In the practical application, the width D 2 of crack 4 can be carried out corresponding setting according to the thickness D1 of different radome 200, when the thickness D1 of radome 200 is 0.10mm, the corresponding width D 2 with crack 4 is set to 0.08mm, when the thickness D1 of radome 200 is 0.15mm, the corresponding width D 2 with crack 4 is set to 0.13mm, and when the thickness D1 of radome 200 was 0.20mm, the corresponding width D 2 with crack 4 was set to 0.18mm.
Further, on described left intermediate plate 2 and described right clamping piece 3 opposite faces, correspondence is provided with left clamping section 21 and the right clamping section 31 of the described radome 200 of clamping, two clamping sections are made of with right clamping piece 3 formed ledge after relative face bending left intermediate plate 2, form described crack 4 between described left clamping section 21 and the described right clamping section 31.This described left clamping section 21 and right clamping section 31 are cambered surface.When described radome 200 was fixed in described crack 4, the both sides of radome 200 were supported respectively in described left clamping section 21 and right clamping section 31, and its form with Line To Line is clamped.Owing to be flat member, have certain elasticity after the bending, so, can realize that the Quick-clamped of described radome 200 is fixed, and solid and reliable.Because the existence of this cambered surface when described radome 200 inserts in the described crack 4, is avoided the described radome 200 of scratch.Certainly, for better clamping described radome 200, can with right clamping section 31 relative sides projection be set respectively in described left clamping section 21, be resisted against respectively the both sides of described radome 200 by this projection, clamp with point-to-point form.
Referring to Fig. 3, in the end of described left intermediate plate 2 and described right clamping piece 3, be respectively equipped with left guide part 22 and right guide part 32 that bootable described radome 200 is installed, described left guide part 22 and described right guide part 32 consist of an introducing port that upwards opens 5.This introducing port 5 is form wide at the top and narrow at the bottom, is one horn-like.When radome 200 is plugged in the crack 4, first radome 200 is placed described introducing port 5, the sidewall with radome 200 abuts on left guide part 22 or the right guide part 32, then again, slip in the crack 4 along this left guide part 22 or right guide part 32, described radome 200 is fixed.So, be version wide at the top and narrow at the bottom by introducing port 5, be easy to radome 200 assembling location, and time saving and energy saving, improved packaging efficiency and positioning accuracy.
Particularly, the middle part of described support chip 1 is provided with the drawing section 6 for the absorption feeding.Referring to Fig. 2, left intermediate plate 2 and described right clamping piece 3 place the place, two ends of support chip 1, the middle part of support chip 1 is not provided with left intermediate plate 2 and described right clamping piece 3, be drawing section 6 but be provided with a plane, so, in realizing automated production, chip mounter can be by the suction nozzle on it, adsorb this drawing section 6, clip 100 feedings are positioned on circuit board 500.Certainly, also can be in the drawing section 6 upwards be convexly equipped with boss, the top of described boss is equal to or higher than the top of described introducing port 7, so, be convenient to suction nozzle and draw, and do not interfere with left intermediate plate 2 and the described right clamping piece 3 of 6 both sides, drawing section.
More specifically, the bottom of described support chip 1 is provided be used to the location division 7 that is fixedly connected with.In this example example, location division 7 is one to be arranged at the plane of support chip 1 bottom.When being fixed in clip 100 on the circuit board 500, fit with described circuit board 500 in described location division 7, namely, the plane of described support chip 1 bottom is fitted on the circuit board 500, like this, increased the contact area of clip 100 and circuit board 500, improved clip 100 and be fixed in intensity on the described circuit board 500.Also can 7 epireliefs establish reference column in the location division, described reference column protrudes downwards along described plane, and on circuit board 500, join and make location hole, so, and by this reference column and location hole, can be with described clip 100 further firm being fixed on the circuit board 500.
The utility model also provides a kind of circuit board, comprise above-mentioned in each clip 100.
Adopt the circuit board 500 of above-mentioned clip 100, clip is assembled in separately on the circuit board 500, fix radome 200, described clip 100 can reuse, and has saved cost, has reduced electronic pollution.
Further, on described circuit board 500, described clip 100 is the diagonal angle and distributes.Referring to Fig. 4 and Fig. 5, when the less radome 200 of assembling area, respectively be provided with two clips 100 in the both sides at the place, diagonal angle of circuit board 500, so, use less clip 100, take less space, described radome 200 can be fixed, save cost of manufacture.
Further, along described circuit board 500 peripheries, described clip 100 is linear array.Referring to Fig. 6, when the larger radome 200 of assembling area, be provided with a circle clip 100 along described circuit board 500 peripheries.So, fix so that each sidewall of radome 200 all is able to clip, it is more firm to connect, and stability is high.
The utility model also provides a kind of electronic product, comprise above-mentioned in each clip 100, do not repeat them here.
Adopt the electronic product of above-mentioned clip 100, make radome 200 be easy to be assembled in the described electronic product, and can utilize the detachable clip radome 200 of this clip 100; with the chip that needs protection in the protection electronic product; highly versatile, simple to operate, cost is low.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
